YARN HEATER Anns'rEA En.

Application filed January 22", 1923. Serial No. 614,213.:

' like material served to knitting or weaving machinery of any character.

The object of this invention is the production of a contriva'nce for heating the yarns-led to knitting machines, and especially spring needle knitting .machines, in such a way as to prevent the yarns from becoming damp or wet, and to provide means whereby any water of condensation that may run down the yarn when steamed Wlll be evaporated by v the heated tube through -which the yarn is passing. This invention in practice is intended to do away with the usual oiling or any other treatment for pro venting breaking, such as blowing dry steam upon the yarn before it goes to the needles. The treatment of the yarn with steam in the practice of this invention softens the yarn, and is believed to fully replace in effect and in operation all methods'heretofore in common use, and to result in a saving of time. One method in use for softening the yarn is to pla it for a certain time in a vapor of oil ort e like. By the employment of this invention the yarn can be used right away without-- losing any time in preparing it for. use. This invention is also obviously adapted for using any mixture of steam and other desired and suitable substances, and.

' is not limited to the use of steam only.

A preferred arrangement of the parts and the construction thereof are illustrated in the accompanying drawings, of which Fig. '1 represents a view chiefly in vertical section, showing all parts assembled. Fig. 2 is an external side view of the casing with the steam and draining connections omitted.

Throughout the drawings and description, the same letter is used to refer to the same part. 4

Considering the drawings, the casing A has its bottom a formed integrally and.

closed. About midway between the bottom and top of the casing is a steam connection B, and a drain connection I) isfarranged in drain pipe 6.

communication with the lower portion of the casing. The top of the casing is closed by a screw cap G. v v

'lVithin thecasing and passing through the bottom a and, the screw cap C steam tight is "the heater tube 0, and near the upper end thereof within the casing will be noted the steam ports 0'. Closing the exposed ends of the heater tube are. the guides or stoppers D and d, through which the yarn d passes on its way tothe'knitting machine.

A drain cock E is screwed into the connection b, and any water of condensation may be permitted to escape byway of the It will be noted in Fig. 1 that the outer end of the valve in the drain con-- nection E is covered by a removable'cap. The valve is thus protectedfrom accidental displacement, which is necessary as the knitv Asbest illustrated in Fig. 1 of the drawings, the screw cap H engages the lower end of the heater tube 0. In this Fig. l is also shown the lower yarn guide comprising the tube It passing through-the screw plug d. It will also be noted that the cap H is constructed to afford a drip chamber J at the lower end of the heater tube 0, and that this p with the steam connection B, and lnclu ing the valve 9.

chamber H is in communication by means of the inclined drain tube 3', with the vertical drain'tube e.

In the operation of this invention, the yarn passes through the heater tube as illustrated, and dry steam is intended to be used; In order to steam the yarn without wetting it, the dry steam is. admitted into the heater tube byway of the ports 0'. If

there is any condensation it runs down the yarn or the interior of the heater tube and is evaporated by the hot tube, or the 5 I I water of condensation collects in the drip.

chamber J and flows therefrom by we of the inclined tube 7'. The casing A is dra ned by the drain valve E in the usual manner.

While the preferred construction and ar-' explains ran ement of parts are illustrated and descri ed in this application, it is thought to be clear that many structural modifications may be devised by those familiar with the knitting trade, without departing from the purview of this invention. 7

Havin now described this invention and g the manner of using it, What ll claim is:- I Y In a device of the character described, the combination with a casing, of a steam connsaaoea nection located midway between the ends of the casing, a draincock connected with the lower portion of the casing, the said casing having its lower end closed and its. upper end provided with a removable screw cap, a heater tube passing steam tight through the said cap and through the bottom of the casing, and yarn guides closing the exposed end of the said tube.

In testimony vwhereof ll afixmy signature.
